JAVA——三个数排序

package jaz;

import java.util.Scanner;

public class sort {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		
		System.out.println("输入num1");
		int num1 = sc.nextInt();
		System.out.println("输入num2");
		int num2 = sc.nextInt();
		System.out.println("输入num3");
		int num3 = sc.nextInt();
		
		int t = 0;
		if(num1 > num2){
			t = num1;
			num1 = num2;
			num2 = t;
		}
		if(num1 > num3){
			t = num1;
			num1 = num3;
			num3 = t;
		}
		if(num2 > num3){
			t = num2;
			num2 = num3;
			num3 = t;
		}
		System.out.println("排序");
		System.out.println(num1);
		System.out.println(num2);
		System.out.println(num3);
		}
		

}

运行结果：

输入num1
999
输入num2
99
输入num3
9
排序
9
